Offset

16 hours

When to schedule

Standard business hours (9 AM–5 PM, Mon–Fri) in Pacific Time and Korea Standard Time don't overlap on the same weekday. Korea Standard Time is 16 hours ahead of Pacific Time.

With some flexibility, there’s a workable window outside standard hours:

  • 3 PM–8 PM in Pacific Time (7 AM–12 PM the next day in Korea Standard Time) — suggest 5:00 PM Pacific Time (9:00 AM Korea Standard Time).

This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.

This window may shift by an hour during daylight saving time.

Public holidays in 2026

National public holidays can affect availability — a counterpart is likely off work on their own holidays, so it's worth planning meetings and deadlines around them.
